Absolutely the coolest app for free. The first thing I tried with it was a complex formula I use in Excel and it smoked. This free version covers all I need, it is awesome. The paid version must be impressive, has to be impressive. Going by what the free version will do, I may buy the paid version just to support the company that created this mind blowing app. 5 Stars are not given, they are totally earned. Great job Quartic Software. A+ I found this great app thanks to "Gizmo's Freeware" site. I give credit to Gizmo's because without them, I may have never heard of RealCalc Scientific Calculator. It will become my all time favorite app.

Not your everyday calculator I downloaded this for school and I have another one for those quick little things. This one is super powerful has all the features I need but my only complaint is how it keeps the decimal as far to the left as possible. I would prefer it to leave it out when there is no decimal (12 is shown as 12.000000000 which makes it a little messy) and keep is as far right as possible. Otherwise I love this one and recommend it.

Great, but... The app is perfect for making just about any calculation you need, and I love that it looks like an actual calculator. However, I don't like that it doesn't display the equation you enter, it only shows the numbers, and then has top or side icons for (+ - × ÷, and brackets, powers, etc). That's the part that I dislike very much. I prefer seeing the whole equation that I'm typing in, not in parts.

BEST CALCULATOR APP This app helps me perform all the calculations I make. But the only problem is that I can't find antilog of a number using this app; so I have to go on to use another source. "Adding the antilog function" would turn my rating to five stars. Otherwise, it is quite convenient to use, so a huge thumbs up :D

Was great, no split screen = uninstall This was my go-to calc app & suddenly it refuses to work with the android split screen. It was able to, & was very handy; now unable to = uninstall. Pro-tip: don't refuse what the end user wants to do if you want to stay relevant.

The best calculator app out there This has to be one of my favourite apps on the play store. Very reminiscent of my college days. Other calc apps are trying too hard by adding too many features or by using screen real estate unnecessarily. This one's the mama bear of calculators. Hats off to Quartic software for creating one that doesn't require ANY special permissions.

RPN capable -- works well As good as any of my favorite HP calculators, and that's saying a lot. Might like to customize some colors and locations and sizings one day, but this one does so much I give the free version 5 stars in the

A long time ago, I knew somebody that had a hundred dollar calculator. I honestly have absolutely no idea how to use this calculator. But I know Walmart has one just like this app, but for a hundred dollars. So, I installed this app. Just for that reason. Its just a smart thing to do I guess. Ill add stuff up later...

Great RPN Calculator In college I used a Hewlett-Packard 42S calculator that I still have on my desk at work. This doesn't have the tactile feel of those old school devices, but it's a great app if you're used to using RPN. I highly recommend it. Better yet - it's free and doesn't have annoying ads.

Very good Calculator App~ For some reason I find myself coming back to use this app over & over across all my devices, I think the UI is sleek & very easy to use. Even if you dont use all the features I still recommend this app!

Great classic-style scientific calculator app. If you're looking for a good scientific calculator and are overwhelmed by the sheer number of awful calculator apps, you've come to the right place. This calculator does exactly what it says it does, and it does it well. It is also very tasteful in asking you to buy the pro version, kudos to developer(s).

Perfect calculator app I've been using this for years now and have finally upgraded to the pro version because although it's not something I use daily, it works perfectly and looks beautiful. It would be one of the first apps I'd install on a new phone and it's been off great use to me time and again. Thanks for a fantastic app.

like my old friend In 1976 I went to the college bookstore and plunked down close to a month's rent for a Sharp "Electronic Slide Rule." Back in the day, that's what we called it if it could do trig functions and logs. I loved it! And Real Calc has the same persona. Everything is so natural. It is more powerful than my old friend but that is acceptable. I have the paid version.

Great app One of my essential applications; one of the first I download on any new device. I'm just having difficulty getting to get the -log of a number. It seems to just return an error message as you have to input a value before you can press the log button. (Never mind. I just had to put the log of the reciprocal. I feel dumb)

Great! Looks and works just like a dedicated, stand alone, traditional calculator. Has all the functions anyone could need. More intuitive than others I have tried - especially the default Android app which is awful - I instantly felt able to use it. Well done, Quartic.

Best calculator app available. A seriously customizable, easy to use and understand, free calculator. What is not to love? This calculator gives one the ability to use the harder functions without becoming too complex for simple users. Great app!

This is a good calculator. It does what I need it to do. I like the look of it, and I like how it doesn't give you the answer until you hit the = button. Almost every other calculator app I tried gives the answer while you're putting numbers in. They make the = button useless.

Sometimes it's a bit confusing when the previous number is not shown when entering a new number after an operator. I think the key pads can be made smaller to make room for two rows that show previous and current numbers entered. This could be optional feature. Another optional feature I think would be helpful is immediate execution mode. For example, when you enter 9-3*2, you get 12.

There are so many better ones I'm doing an strophysics degree so having a good calculator on my phone is pretty important. This is not it. You are unable to see the formula you're typing in which makes it IMPOSSIBLE to find a mistake. Also the sin function is no longer accurate at 0.001 rad (pathetic) I'm actually surprised that finding the square root of a number and then squaring it back gives the correct answer. If you need a scientific calc, get something esle. If you want a simple calculator, there are still better options.

Good app. But one annoying little gobbledygook. . So far, very good app. My only complaint is the decimal point key is to the right of the +/- key so that it is not next to the numbers with the +/- key in the middle. How many times do I hit the +/- key when I want to type a number with a decimal...? I need a calculator to compute that! Especially problematic when typing quickly. Very annoying. Can you just swap places between the decimal point and the +/- key? A simple thing like that would make this a 5 star app!

The best scintific calculator as app ever. I have tried a lot of math calculators and none of them are this light weight working pefectly on any phone and with a cool realistic fesign and pefectly acurate calculations. I have used this app for 4 years now and both the old and the new vesion is great. Fast relaiable and good. GREAT JOB GUYS your app should be higher listed in the math app lists.

Realistic The closest to a real scientific calculator you'll ever get, probably even better. Would like to have statistical functions (average, deviation, etc.) as well. An option for financial calculator would be nice too.

Exactly what you'd expect This calculator does exactly what it's supposed to do. It resembles a real (Texas Instruments) calculator as closely as it possibly could. I love how clean and organize the interface is - just like a real calculator's look and feel. No nonsense, no ads, but all the functionality that can be expected from a calculator. I love it!

intuitive Ui I'm waiting for the other shoe to drop, like so many perfect apps which developers feel the urge to wreck by making unnecessary changes! Dev, you've done a great job please work on something else!

Old School ! Takes a little getting used to because of its extensive features. (It's been a while since college when I last used one of these in real life, lol). But it has a good help function. Every function you can think of, and then some.

Awesome app, can get even better. Finally I found the app which I needed the most. Its working fine for me and I consider myself lucky to have found this app. But I believe it can get even better if there is an addition of mode button to change the calculator's mode like in a real scientific calculator..

Exactly what it says on the tin It's simply a classic, nice-looking, easy to use scientific calculator. Does what it says, doesn't try to be overly fancy or have unnecessary features. It's what I would expect out of a nice scientific calculator I'd buy at a store.

Pretty great! So the fact that you can't see your full equation is a little annoying, but no big deal, but this app has no extra permissions (as any simple calculator should) and therefore, no usless caller ID! You might ask yourself, why would a calculator have caller ID??? Tbh im just as confused as you are, but you'd be surprised to find that that exists. It's dumb I know. But this app isn't like that! It's actually good! You need a free calculator app? Get this one. Trust me.

Great calculator, annoying upgrade notices It's a good calculator, and ad-free, which is good. But the constant (literally every time I start the app) nags to upgrade to the paid app made me find an alternative.
